Notification Systems and Methods That Permit Change of Time Information for Delivery and/or Pickup of Goods and/or Services

Systems and methods are disclosed for automated computer-based notification systems. A representative method, among others that are disclosed herein, can be broadly summarized by the following steps: engaging in a first one or more data transfers with a first personal communications device (PCD) for scheduling an order relating to arrival or departure of a mobile thing (MT) at a stop location and to pickup or delivery of a good or service at the stop location; during the first one or more data transfers, requesting and permitting input or selection of time information relating to the pickup and/or delivery of the good and/or service at the stop location; permitting the MT to arrive at or depart from the stop location based upon the input or selection of the time information; causing initiation of a second one or more data transfers with the first PCD or a second PCD designated during the first one or more data transfers, prior to expiration of the time information related to the pickup or delivery of the good or service at the stop location; and during the second one or more data transfers, permitting a change to the time information associated with the order that was established during the first one or more data transfers; and permitting the MT to arrive at or depart from the stop location at a later time based upon the change in the time information that was established during the second one or more data transfers. A representative system, among others, can be a computer system that has been programmed to perform the foregoing steps.
